Mitsubishi Pencil's best-selling ballpoint pen, Jetstream, replacement front section. Changed from the standard rubber specification to a wood specification. It will be an easy-to-handle, one-of-a-kind custom ballpoint pen that fits comfortably in your hand and is different from others. The wood specification is made of precious Karin burl. Karin burl is a burl (knot) material that can only be harvested from a part of the root of the Karin tree, and has been a popular wood species for high-class crafts since ancient times. Its grain is very beautiful, and the various patterns created by the intricately intersecting grain can truly be called the beauty of natural sculpture. Currently, imports have stopped, making it a very rare and difficult wood species to obtain. The dimensions of the Karin burl are almost the same as the genuine rubber. This is only the front section; the ballpoint pen body is not included. If you would like the ballpoint pen body included, please comment. Also, if you would like other wood species, please comment. Please refrain from price negotiations. I have also listed various other items. Please take a look if you like. #KoboMatch Thank you. #Jetstream #Jetstream4&1 #JETSTREAM4&1 #Multi-function pen #Multi-function ballpoint pen #Wood grip #Wood shaft custom #Replacement front section #Mitsubishi Pencil #KoboMatch
